(from Kleemann Press Release) The all new KLEEMANN SL 55 Xtreme concept. Kleemann is introducing a line of exciting special edition vehicles based on different Mercedes-Benz models.

The KLEEMANN SL 55 Xtreme is the first special edition vehicle to leave the Kleemann production facility. Although originally based on the chassis of the Mercedes-Benz SL 500 and the naturally aspirated 5.5 AMG engine, the resemblance to the afore mentioned vehicles and engines however ends.

Production of the KLEEMANN SL 55 Xtreme will be limited to just 20 units. In production form, the limited edition will be based on the SL 55 AMG, guaranteeing a high tech product that not only is unique but also highly exclusive.

The first edition vehicle from KLEEMANN features advanced aesthetics combined with innovative design and superior technical know how. The latest in the line of ultra refined KLEEMANN Kompressor systems produces 640 Hp at 5.800 rpm and 835 Nm between 2.000 and 6.000 rpm. The KLEEMANN Kompressor runs at 0,75 bar which is 0,15 bar lower than the originally fitted kompressor system from AMG. However due to better airflow, the KLEEMANN Kompressor produces 35 % more power. The performance of the finished product is second to none.

With an electronically limited top speed of 330 km/h and an acceleration from 0 - 100 km/h in just 4,4 seconds, the SL 55 Xtreme has class leading performance. With huge power reserves, a high performance braking system could not be overlooked. The 55 Xtreme features a high efficiency braking system that guarantees perfect stopping performance regardless of the conditions.

Both the exterior and interior of the SL 55 Xtreme are something to behold. The word Xtreme is something of an understatement when one considers the many interesting features of the vehicle. Eye-catching scissor doors provide a very characteristic appearance of the SL based car that truly lives up to the name Xtreme. The door mechanism is fully automated and can be activated by the touch of a button on the keyless remote control or on the dashboard inside the car. In practical terms the doors provide full usability and greater flexibility when opening or closing compared to conventional doors. When opening the scissor doors, they only require a 60 cm opening radius compared to the traditional opening radius of 110 cm on a conventional door.

The characteristic KLEEMANN front spoiler has been modified with a carbon fibre lip that underlines the sporting intent behind the design as well as creating better down force and stability at high speed. The rear spoiler has also been modified. Two extra fins on the diffuser channel improve airflow behind the vehicle and provide more down force and stability at high speed as well as during heavy braking.

The interior of the SL 55 Xtreme is in a class of it's own. The interior is covered in alcantara and soft Nappa leather. Detailing such as black carbon trim and a beefy sports steering wheel also provide that exclusive touch.

The seats of the Xtreme are likewise indicatory of and specially designed for the limited edition vehicle. The seats match the sporty exterior while retaining original features such as pulse, ventilation and electric movement which are found on OE seats. Without compromise to comfort and well being, the contour of the seats provides for a more sporty and involved driving experience.

The Mercedes-Benz SLR McLaren is one of the world's most fascinating sports cars. The best Mercedes is just good enough for Brabus, and their engineers have developed an exclusive sport program. It lets owners of the SLR further individualize their vehicles.

Brabus equips the SLR with a special self-locking differential. Its 40 percent locking rate further optimizes the supercar's traction and thus further improves acceleration.

In Brabus Racing version with performance-improving fuel cooling, custom camshafts and an open racing exhausts system maximum power output of the supercharged V8 engine increases to 660 hp / 486 kW at 6,500 rpm. The exhaust system is not certified for use on public roads. Thus equipped the SLR storms to 100 km/h from rest in just 3.6 seconds and reaches a top speed of up to 340 km/h.

Brabus further offers professional modifications to body, suspension and interior that further amplify the sports talents of the SLR.

For further improved directional stability at high speeds the Brabus designers developed a new spoiler for the front air dam. The exposed-carbon aerodynamic-enhancement part reduces lift on the front axle and adds another shot of racing looks. The rear diffuser is also made from exposed carbon.

The multi-piece Brabus Monoblock VI 20-inch light-alloy wheels with six double spokes command immediate attention. The fully polished wheels in size 9.5Jx20 in front and in size 11.5Jx20 on the rear axle fill out the available space below the wheel arches perfectly.

Brabus also adds new sporty and exclusive highlights in the interior. The company-own upholstery shop created a Brabus interior from an exclusive black and red combination of leather and Alcantara, perfecty crafted down to the last detail. The waffle-design stitching of the SLR leather floor is especially elaborate and it alone uses 7,800 meters of the finest thread.

For easier entering and exiting Brabus manufactured a custom Brabus sport steering wheel with an ergonomically shaped rim that is flat on the bottom. For manual shifting of the SLR's automatic transmission the Brabus steering wheel features buttons integrated into the spokes.

The Brabus interior designers developed precise-fit applications for dashboard, center console and door panels, all made from exposed carbon. They extend the Brabus exterior carbon look into the interior.

The Brabus SLR sells for 600,000 Euros (790 000 USD). Included in the price is the SLR's air-freight shipment to anywhere in the world.
